Scanning Probe Microscopy
The research group scanning probe microscopy (SPM) has been established with a focus on high-resolution local structure measurements on model systems for heterogeneous catalysis. Well defined crystalline and amorphous thin oxide film systems have been developed and characterized by atomic resolution scanning probe microscopy and spectroscopy to gain insight into local structural environments for chemical reactions taking place at these surfaces.
Electrocatalytic reactions, such as water oxidation and carbon dioxide reduction, that are being pursued by the Department of Interface Science could be significantly affected by the use of these films on the surface of the catalyst. Stabilization of the catalyst from degradation and erosion is an ongoing area of interest. Furthermore, modification of metal single crystal electrodes with a two-dimensional barrier layer is proposed as a model system to address structural and chemical alterations that could occur during electrochemical reactions that might lead to changes in their activity and selectivity. Chemical and structural effects created by two-dimensional overlayers is a hot topics in this research direction.
